Contact lenses are capable of correcting most of the problems that spectacles can as well as some additional ones that glasses cannot.

People not satisfied with their appearance using glasses can opt to use contact lenses for improved appearance. Contact lenses are not in the danger of slipping off, getting wet, or fogging up, which can easily happen with spectacles.

Extremely hypermetropiac people or those who have had cataracts removed, feel better wearing contact lenses as compared to spectacles, which in these cases produce uneven vision. Moreover, contact lenses give improved vision for people with damaged corneas due to disease or injury. Also for sportsmen, wearing contact lenses prove to be more practical as in the case of those where wearing spectacles pose a problem in their jobs. In addition to all these, contact lenses provide better side vision compared to glasses.

Uses of Contact Lens

The primary use of contact lenses is to correct myopia (short sightedness). They can also be used to rectify hyperopia, astigmatism, presbyopia and aphakia. Rigid lenses are used to correct irregular corneal trauma. Soft lenses are used as bandages for conditions like bullous keratopathy, recurring corneal erosion as well as to increase comfort, vision and postoperative wound healing.

TYPES OF LENSES AVAILABLE AT EYE Cornea Foundation

Daily Disposable Contact Lenses

Daily disposable lenses are the most popular contact lens for many reasons. They are convenient and easy to use because you don't have to hassle with cleaning. They are also healthier for those with allergies because they are hygenically clean every morning. Please consult your eyecare specialist for advice.

Monthly Disposable Contact Lenses

These contacts can be worn for up to one month, as directed by your optometrist. This means that at the end of every day you remove your lenses and clean them before reinserting them.

This is because your tears contain mineral deposits which can build up on your lenses. If you do not clean them properly then these deposits can cause discomfort and even infection.

Toric Contact Lenses

Toric Lenses are designed for those with astigmatism. A toric contact lens has two different powers or curvatures so that it can correct for both astigmatism and either myopia (near-sightedness) or hyperopia (far-sightedness). Increasingly, toric contact lenses, which typically combine the effects of a cylindrical lens with that of a spherical lens, are being prescribed for people who are astigmatic and also need help with their far-away or close-up vision.
